"Offer codes for in-app purchases are a powerful new way to run promotions, give free or discounted access, and engage with customers. Set customer eligibility and expiration dates for up to 1 million codes per quarter. Starting March 26, 2026, offer codes will replace promo codes for in-app purchases, excluding app-level promo codes. For auto-renewable subscriptions, you can now create offer codes that won't auto-renew after the promotional period"

Didn't know IAP promo codes were going away!

Offer codes actually seem pretty legit; you get a million of them every quarter, you can provide custom pricing for your IAPs and subscriptions that you can give to individual customers, and you can even do human-readable in-app code redemption for special pricing and discounts. I wasn't /at all/ aware Apple was moving to this system wholesale by next week
The most interesting thing about Apple's Offer Codes system, I think, is that they effectively give you, as a developer, the ability to let customers name their price for subscriptions, if they ask nicely. I'm sure many developers would be happy to have a subscriber vs a non-subscriber, even if it's not at full list price. The only problem is Apple forces you to generate at least 500 offer codes at a time, no lower
@stroughtonsmith I’ve been thinking about using these as a way for existing subscribers to share/gift discounted prices with family and friends. It’s a link after all that can be presented to them that they can forward. Pocket Casts offers something similar for pro users.
